Existing comment: The dogs had color-coded collars. A green collar meant people could try to pet him. A different color (white?) meant you could pet him but there might be issues (he might pee all over you or something). Another color (red?) meant don't bother trying to pet him because he might try to kill you. They also had to worry about pack structures with dogs -- alpha, beta, and omega dogs had to be balanced in each pack. And some packs got too comfortable and wouldn't accept any new members.
